On the definition of angle stability in power systems with grid-forming power converters
This letter illustrates the paradigm that, in a power system with both synchronous machines and gridforming voltage source converters (GFM-VSC), the stability phenomenon related to the ability of generators to remain in ... -
Active-power control strategies in grid-forming power converters to improve transient stability in power systems with 100 converter-based generation
Grid-forming voltage source converters (GFMVSCs) are among the technologies that play a crucial role in supporting system dynamics. In systems with a high proportion of GFM-VSC-based generation, transient stability becomes ... -
Framework for Climate-Resilient Low-Carbon Transport: Application to Spain
Transport decarbonisation, especially through electrification, increases the interdependence with the wider energy system, thereby amplifying climate vulnerability. We propose a framework that represents the interactions ... -
Beyond green hydrogen: the role of low-carbon hydrogen in the optimal operation of electrolytic plants
Renewable and low-carbon hydrogen are expected to play a central role in Europe’s transition toward climate neutrality. Understanding the economics of hydrogen production is essential to ensure its large-scale deployment.Most ... -
Exploring the synergies of biomass-based top-cycle CHP plants with hydrogen for industrial applications
Combined heat and power plants (CHP) maximise the usable energy from combustion processes. By providing both usable heat and electricity, it is a flexibly adjustable technology based on demand profiles from industrial ... -
Biomass top-cycle CHP with hightemperature heat pump coupling: economic insights for industrial decarbonization
Over half of the final energy consumed by the European industrial sector relied on carbon-emitting fuels in 2022. Biomass-based cogeneration technologies can efficiently adjust to varying industrial electricity and heat ... -
Thermal performance assessment of closed-loop geothermal heat exchangers with vertical, inclined, and curved boreholes
Accurate sizing of closed-loop geothermal heat exchangers is crucial to ensuring the energy efficiency and cost-effectiveness of shallow geothermal HVAC systems. One common design limitation is the restricted surface area ... -
Tackling uncertainty in electrolyser deployment: the role of degradation on expansion planning problems
Uncertainties surrounding the long-run cost-benefit of hydrogen hybrid plants (i.e., dedicated renewable power, energy storage technologies, and grid connection) are challenging the widespread adoption of electrolysers, ... -
Context Trails: A Dataset to Study Contextual and Route Recommendation
Recommender systems in the tourism domain are gaining increasing attention, yet the development of diverse recommendation tasks remains limited, largely due to the scarcity of public datasets. This paper introduces Context ... -
How did the energy crisis affect household electricity consumption? Assessing electricity demand elasticity in Spanish households
Residential electricity demand is widely recognised as structurally inelastic. However, this claim may not hold in the future – at least in most liberalised electricity markets. Among other factors, a higher exposure to ...
